Final Report: Pilot-Scale Cross-Flow Ultrafiltration Test Using a Hanford Site Tank 241-AN-102 Waste Simulant

[摘要] Bechtel National l, Inc. (BNI) has been contracted to design a Waste Treatment and Immobilization Plant (WTP) to stabilize liquid radioactive waste that is stored at the Hanford Site as part of the River Protection Project (RPP). Because of its experience with radioactive waste stabilization, the Savannah River Technology Center (SRTC) is working with BNI to help design and test certain parts of the waste treatment facility. One part of the process is the separation of radioactive solids from the liquid wastes by cross- flow ultrafiltration. This task tested a cross- flow filter, prototypic in porosity, length and diameter, with a simulated radioactive waste, made to prototypically represent the chemical and physical characteristics of a Hanford waste in tank 241-AN-102 (AN-102) and precipitated under prototypic conditions. This report discusses the results of cross- flow filter operation in a pilot-scale experimental facility. This filter technology was evaluated for its inclusion in the pretreatment section of the nuclear waste stabilization plant being designed by Bechtel National, Inc. The waste treatment plant will be built at the U.S. Department of Energy's Hanford Site as part of the River Protection Project.
